Answer:
O Feathering
Explanation:
Feathering refers to the technique by which large flowers are cut into small pieces, which are then used to create smaller flowers. Feathering consists of removing the petals and wire the petals in order to create a smaller form. Carnations are a type of flower in which feathering is applied. This process was widely used by florists in the past but currently is uncommon due to the excessive time and labor involved in this technique.

See the answer below
Explanation:
<em>When an object on a sample slide can be perfectly focused at lower objective but cannot be focused at higher objectives, the problem can be attributed to two factors depending on the size of the objective</em>:
1. At 40X objective, the most likely problem would be that the object on the sample slide is not in the center of the field. Adjusting the slide until the object on it is at the center of the field would likely solve this problem.
2. At 100X objective, the problem could also be that the object on the slide is not at the center of the field, could be that there is no immersion oil on the slide or a combination of the two factors. Dropping an immersion oil on the slide and adjusting the slide to bring the object on it to the center would solve this problem.
If you're referring to wing color in terms of evolution, wing color can be determined by something as small as the color of trees that particular bird is around. Those with wings that match the tree color are most likely to survive because they are more hidden from predators.
Answer:
The correct answer will be option-Crossover region
Explanation:
Recombination is a complex process which leads to the exchange of the genetic material between sister chromatids.
The recombination process is mediated by the recombinase enzyme which recognize the specific sites and allows the formation of the protein-DNA complex called synaptic complex.
The synaptic complex contains the short asymmetric sequence called the crossover region, which represents the rejoining and the DNA cleavage site.
Since crossover region represents the recognition sequence which is flanked is known as the crossover region.
Thus, the crossover region is the correct answer.
Answer:
Trophic cascade is defined as an ecological phenomenon triggered by the addition or removal of top predators and involving reciprocal changes in a relative population of predators and prey through food chain, which often results in dramatic changes in the ecosystem structure and nutrients cycling.
Explanation:
An example was the removal of wolves in Eastern North America which was associated with an increase in white tailed deer and a decline in plants eaten by the deer.
